[SOLVED] PC to 65" tv 4K wanted but tried 3 tvs now, not good.

Had a 50" digihome for 18 months, no problem on my system.
AO sold me a TCL but it wouldn't do 4K at all. Refunded.
Argos Bush Fire 65 would only do 4K at 30hz. exchanged for
Bush QLED 65 same as TCL, no 4K at all.

For each tv, I have tried a lot of things, been around pc builds since pentium one. Win10 and 11 on each tv, no difference.

My budget is low so does anyone know a budget 65" that is capable ?

What? Huh? What are you trying to accomplish? What are the specs of the PCs being used?

4k 60hz minimum on a 65" screen. pc spec is easily capable as it worked on a digihome 50" but 10th gen 64gb ram 1650super. As I say, it all worked fine on the 50" but the best I got on the 65" inchers was 4k 30hz on the bush fire 65 tv

So I moved to a Hisense 65" and had exactly the same problem. The only thing left to try was possibly another HDMI lead. I know mine did the 50" at 4K 60hz on this pc setup. It did the one bush QLED at 4K at 30hz but no higher too. So I next dayed a 8K lead from scamazon.

BOOM : Problem solved. My pc is now connected at 40K 60hz.

I have fed the results back to Bush, out of courtesy which they were very intrigued by, we chatted for over 30 minutes about all the attempts and such. But it was clear that:

HDMI 2.0 lead should support 4K at 60hz
HDMI2.1 supports 8K at 60hz or 4K at 120hz

yet it took the 2.1 lead to fix this.
